CVE-2026-76185
Published:November 09, 2026
Updated:November 09, 2026
Apache Airflow's Task SDK secret cache built its keys from the team name and secret id with unescaped "_" delimiters, so different (team, secret id) pairs could collide. In multi-team deployments a Dag author could read another team's Variable or Connection value by crafting a colliding secret id. Only deployments with both "core.multi_team = True" and "secrets.use_cache = True" are affected.
Users are advised to upgrade to apache-airflow 3.4.0 or later. Deployments that cannot upgrade can set "secrets.use_cache = False".
